WILLIAM B. GROOKEB, OF NEW YORK, N. Y.

DIPPING-MACHINE.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed May-5, 1908. Serial No. 430,906.

T 0 all whom it may concern:

Be it known that I, WILLIAM B. ORooKnR, a citizen of the United States,and a resident of the city of New York, borough of Brooklyn, in thecounty of Kings and State of New 1 York, have invented a new andImproved I represented in the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicate,corresponding parts in all the views.

Figure 1 is a transverse section of the improvement; Fig. 2 is asectional front elevation of the same on the line 22 of Fig. 1; Fig. 3is an enlarged plan view of one of the trays; Fig. 4 is a like view ofthe same and showing the biscuits 0r cakes in position on the tray; Fig.5 is a similar view of the tray showing the biscuits or cakes inposition on the tray and the marshmallows supported on the biscuits orcakes; and Fig. 6 is an enlarged sectional side elevation of the same.

On a table or frame A is set a pan B forcontaining chocolate, icing,cocoanut or other coating material C used for coating marshmallows Dattached to biscuits or cakes E held on retaining devices F, preferablyin the form of staples driven in the tray G, of a size somewhat lessthan the pan B, to permit of placing the tray into the pan B, as shownin-Figs. 1 and 2 and as hereinafter more fully described. The retainingdevices F project from the face of the tray G, i

and each retaining device is arranged within a field G laid off on theface of the table G by suitable lines or other means, as indicated inFigs. 3, 4 and 5. The retaining devices F project a sufficient distancefrom the face of the tray G for receiving a biscuit or cake E, as shownin Fig. 4, it being understood that on each biscuit or cake E is placeda marshas indicated in Fig. 6. The biscuits or cakes E and themarshmallows D superimposed on the said biscuits or cakes, may be placedin position by hand or by suitable mechanical devices.

After the tray G is filled with the cakes E and the marshmallows Dsuperimposed thereon, then the tray is turned upside down and placed inthis position on transverselyextending supports H, in the form of bars,extending transversely in the an B, above the level of the coatingmateria O contained in the said pan. The supports H are provided attheir rear ends with upwardlyextending arms H attached to slides I.mounted to slide up and down in suitable guideways arranged in standardsJ erected on the table or frame A. On the slides I and preferably at theback thereof are secured or formed racks l in mesh with gear wheels Ksecured on a shaft L journaled in suitable bearings arranged on thestandards J, and on the shaft L is secured a ratchet wheel N engaged bya pawl O, to hold the ratchet wheel N and consequently the shaft Lagainst turning, with aview to support the tray G the desired distanceabove the coating material O contained in the pan B. On one end of theshaft L is secured a crank arm L under the control of the operator, topermit the latter to lower the supports H and consequently the tray G,with a view to bring the tray always into the pro er relation relativeto the coating materia C as the latter is gradually used up. It isunderstood that when it is desired to lower the supports H and the trayG, the operator first disengages the pawl 0 from the ratchet wheel Nbefore turning the crank arm L with a view to lower the slides I and thesupports H. On the rear end of the pan B and approximately midwaythereof is arranged a rest P projecting forwardly, to permit theoperator to rest the rear end of the tray G on the said rest with a viewto allow the surplus material to drip back into the pan B.

The operation is as follows: When the tray G has been filled with thebiscuits or cakes E with the marshmallows superim osed thereon, then thetray is turned upsic e down and placed with its sides on the supports H,so that the marshmallows are immersed in the coating material Ccontained in the pan B. In practice, the supports H are adjusted in sucha manner that the level of the coating mallow D, preferably ofsemi-spherical shape, 1 material C is close to the under surface of thebiscuits or cakes E, so thatth'e coating material covers themarshmallows only, without the supports H, and then the rear end ofthetray is rested for a short time .on-itherest :P,

so that the surplus coating material C can drip back into the pan B, andthen the't'ray with the coated marshmallows thereon is turned over, toallow the coating materialto set and dry, after which the biscuits orcakes E with the coated marshmallowsthereon are removed from the restingdevices l As previously stated, the supports H are lowered from time totime to compensate for the used up coating material contained inthepanB.From the foregoing it will be-seen tlratby the arrangement described alarge number of marshmallows can be quickly and uniformly coated with asuitable coating material and Without danger of submerging the biscuitsor cakes in the'coat-ing material.

Having thus described my invention, I claim as new and desireto secureby Letters Patent: 1. A dipping machine for coating marshmallows held onbiscuits or cakes, comprising a pan for containing the coating material,an adjustable tray support above thelevel oi the coating materialcontained in the said pan, and a tray adapted to be placed on the saidtray support in an upside down position, the'tray having spacedretaining devices on one face for entering and supporting the cakes andthe marshmallows to be coated, the said retaining devices 'allowingreversal of the trav with the cakes and marshmallows suspended therefromfor (lipan adjustable tra retaining devices to which the mars-hmal-lowsare attached,

ping the marshmallows in the coating material contained in the said pan,2. A dipping machine for coating marsh mallows held on biscuits orcakes, comprising aipan=for containing the coating material, anadjustable tray support above the level of the coating materialcontained in the said tray with cakes and marshmallows suspendedtherefrom, for dipping the marshm-all'ows-inthe coating materialcontained in the said pan, means for raising and lowering the said traysupport, andmeansfor limiting the downward movement of the said traysupport, 'to *control the depth 'the marshinaljlows pass into thecoating material.

3. A dipping machine'for coating-marsh mallo'wsheldon biscuits or cakes,comprising "a" pan for containingthe coating material,

y-support in the'sa-id pan, a tray adapted to rest on'the said supportand provided on its-under sidevwith spaced for the biscuits or cakes and-a bracket on the said pan for resting one end of thetrayt'hereon,toal-loW-' the surplus coatingmaterial to drip) back into thepan.
